When I download torrents with comcast, it bounces from 3 meg to 1 meg, then to 0 meg and stalls for a couple of minutes before going back up to 3 meg and starting the cycle all over again.
Johnny, if you're still getting speed rate jumps and halts it may be your modem. I had a similar problem for about a year before I got a service rep who told me to get a new modem. I finally did and the issue disappeared.
Funny thing is the issue didn't show up on speed checks or regular downloads, it only happened on torrents. There may be a heavier load on the electronics causing heating of the modem and data loss. All I know is the tech rep was right (for once).
Another time some workers damaged my buried cable. That actually showed up on the phone more than the data line (DSL).
Yep, I downloaded "The Office" without using my seedbox and got an email the next day. Since I've used the seedbox I haven't heard anything so I assume its all good. I also download from only private trackers.I downloaded a tv show the other day with bittorent and got a copyright infringement notice from comcast the next day. They are watching, so be careful. The notice they sent me was just a thing saying to stop downloading. But it scared me none the less. I have since took bittorent out of my computer.
